Low Loss Dielectric Materials

2021
Semiconductor industry has identified five major growth engines (applications) [1, 2]: (1) mobile such as smartphones, smartwatches, notebooks, wearables, tablets, etc., (2) high-performance computing (HPC), also known as supercomputing, which is able to process data and perform complex calculations at high speeds on a supercomputer, (3) autonomous ...

Dielectric loss in boron

Journal of the Less Common Metals, 1979
Abstract The temperature dependence of the dielectric loss (tgδ) in β-B was studied at temperatures ranging from −196 to 350 °C and at frequencies of 1–104 Hz. The curve of the temperature dependence of dielectric loss in an electric field with a frequency of 50 Hz showed two relaxation maxima at −65 and −45 °C characterized by activation energies of

Low-loss dielectrics

Journal of Materials Science, 1999
Low-loss dielectrics are important technologically as insulators but there is little understanding of the physical causes of this property and even their spectral response is not well documented—this study has revealed a number of different types of behaviour which do not appear to have been recognised previously. Most low-loss materials show a “flat”,

Measurement of Dielectric Loss and Wall Loss in a Dielectric-Filled Waveguide

IEEE Transactions on Instrumentation and Measurement, 1974
A waveguide bridge capable of measuring dielectric loss down to 5 ?rad at frequencies of 10-35 GHz is described. A major uncertainty was the value of the wall loss. This has been resolved by measuring the wall loss of the specimen arm both with air and dielectric filling.

Loss Mechanisms in Dielectric-Loaded Resonators

IEEE Transactions on Microwave Theory and Techniques, 1985
Analysis is presented of resonators consisting of a section of a dielectric-loaded waveguide shorted at both ends. The analysis includes resonant frequency calculations, mode charts, and unloaded Q computations. Numerical results are presented for the unloaded Q's of various modes, as a function of the resonator parameters.
